The non-aqueous electrolyte secondary battery, in which decomposition of the electrolyte is reduced, exhibits high coulombic efficiency and excellent charge / discharge cycle performance, and has a high energy density. This non-aqueous electrolyte secondary battery is a negative electrode formed by forming an active material thin film on a current collector by CVD, sputtering, vapor deposition, thermal spraying or plating, and the active material thin film absorbs and releases lithium, and in a thickness direction. A cathode which is divided into pillars by cracks formed, and each lower portion of the pillars is bonded to the current collector; A cathode capable of absorbing and releasing lithium; And a non-aqueous electrolyte containing a non-aqueous solvent and a lithium salt dissolved therein. This electrolyte solution contains the compound represented by the following general formula (I).n n n n n n n n (Wherein R 1 , R 2 and R 3 are each an alkyl group or a hydrogen atom having a substituent depending on options, and may be the same or different from each other, may be independent substituents, or may be bonded to each other to form a ring) have.) |
